sketch ideation

i started coming up with ideas on the form with hand sketches via procreate. i chose the omnidirectional and double form since they represent B&O’s form language. <click to scroll through>

//01 cardboard

i made cardboard mockups for the 2 chosen sketches. i chose to move forward with omnidirectional since it effectively hides the speaker parts.

//02 mdf and black foam

i changed both the proportions of the speaker with the black foam and the way it was held up with the mdf to get a feel for proportions.

Frame-19

//03 10 lb foam

I fitted all the parts into a prototype. The thin dowels did not hold up the weight of all of the parts very well, so i had to make the dowel thicker.

//04 fabrication

I made an acrylic encasing for the aux PCB board and used bondo to fix it onto the foam.

Frame-23

I sanded down the foam encasing before priming the speaker and fitting the parts.

Frame-24

I spray-painted all the parts before attaching the electrical components. 

Frame-25

//05 final assembly

i assembled the painted parts into the 4 subassemblies before finally screwing everything together.
